V UNITED STATES PATENT OFFICE. PETER WEEE oF ORANG NEW JERSEY, Ass1eNoR TO NEW JERsEY PATENT COMPANY, or WEST ORANGE, NEW JERSEY, A coRPoRA- 'TIoN on NEW E SEY l=.HONOGRAPH.

Be it known that 1,.PETER WEBER, a citizen ofth'e UnitedStates, residing at Orange, in the countyof Essex and State of New J ersey, have invented certain Im rovements in- 7 Phonographa of which the fol owing is a deprotecting and adj isti 'scri' tion. j 4

yinvention relatesto phone aphs, and

has or its object the provision 0 means for the spring used for carrying the-'feednut by which the traveling carriage is given a progressive movement.

In. :phonographs of the Edison type this spnng'issecured at its rear end to the carriaige andextends forwardly therefrom, and 1t equently happens that persons who are ignorant ofthepro e'r manipulation of the machine make use 0 the 'said spring for raising the carriage when it isdesired to change the' recordmn the mandrel.- In this way the s ring frequently becomes bent so that it' oes not properly hold the. feed-nut upon the I feed-screw. It'is. desirable, therefore, that means be provided for preventing such injury even though the spring be usedfor this purpose. It is also desirable that means be provided for adjusting the free end of the said spring in a downward'direction, so that any desired pressure of the feed-nut upon the screw may be obtained. With these ends in view In invention consists in the features hereina ter described and claimed. Reference is hereby rn ade to the accompahyin-g drawings, in which a Figure 1 is a plan view illustrating an embodiment of my invention; and Fig. 2 is a side elevation, partly in section, of the same.

Corresponding parts are designated by the same numerals of reference in both views.

In the drawings, '1 represents the main shaft of a phonograph, which is providedwith a feed-screw 2 of narrow pitch and carries the usual mandrel 3 for supporting the record.

' 4 is the usual back rod, upon which the traveling carriage or sup ort 5 is sleeved and to which the rear end 0 the feed-nut spring 6 is secured. This spring carries at its'free end thefeed-nut 7, which normally engages the feed-screw 2. A guard 8 is situated above'the spring 6 and extends close to said spring at its free end, so that if the spring is T Specification of Letters Patent. Application filed October 21,1905.

of the same will cause it to press against the end of the guard, which then carries the weight of the parts.and prevents. furtherbending of the sprin or, in other Words, it greatly shortens the Ie spring by the weight of the parts.

.The' guard '8 andspring 6 are preferably securedto the carriage 5 by screws 9 9,which pass through the guard and spring'and are threaded in the said carriage.

In order that the free end of the sprlng 6 -may be adjusted downwardly, an adjustingscrew 10 is threaded in the guard 8, passing through the same and abutting against the top of said spring, as shown in Fi 2. Obviously a downward movement 0 this'screw will increase the pressure of the feed-nut 7 upon the'screw 2.

verage exerted on the Having now described my invention, what I claim as new, and desire to secure by Let'- 1. In a phonograph, the combinationof the feed-screw, back rod and sup ort traveling on said back rod, of the ,fee {nut spring secured at one end to said support, and a rigid guard carried by said support and extending close to said spring at its free end,

substantially as set forth.

' 2. In a phonograph, the combination ,or

the feed-screw, back rod, and-support traveling on said back rod, of the feed-nut sprin secured at one end to said support, a rigic guard carried by said support and extending close to said spring at its fiee nd, and a de vice cooperating with said guard for adjust-v in the free end of said spring downward, substantially as set forth.
